WOVEN FABRIC.

scription.

My invention relates to the improved construction of a fabrichereinafter clearly shown and described; and it consists in combining ina fabric an inlay-thread with certain warp and weft threads andiigurecords, all securely looked, as hereinafter more fully described.

The object of my invention is to construct a fabric the faces of whichare formed by ornamental or other cord, which is securely locked inplace by warp and weftthreads, one side of which may be one color andquality while the opposite side may be of another color and quality.

' My invention is illustrated by the accompanying drawings, in whichFigure 1 is a diagrammatical enlarged face View of the fabric.

Fig. 2 is a similar bottom or reverse view of said fabric.

Fig. 3 is a similar cross-section on the line 3 3, Fig. 1. F1g.41s asimilar longitudinal section on the line 4 4, Fig. 1.

Fig. 5 is a cross-section of part of a loom on which the fabric can beproduced.

9' 7' represent the ornamental or other cords which form the faces ofthe fabric.

a b are the main warp-threads,which interlock in the mannerhereinafterdescribed and hold the cords jj into the fabric.

0 is an intermediate warp-thread, which passes between the cords jj andserves to make the fabric even.

third cord j, and so on.

The lower warp- SerialNo.393,806. ($pecimens-l thread 19 goes around thelower cord 3' up around the thread 3, down around the next cord j and soon. The warp-thread c is above so the weft-threads 33, as shown. B ythis method it will be seen that a fabric having its opposite sidesdifferently colored may be readily made by having one cord jof onedesired color and quality and the other cord 3' of another desired colorand quality. In the finished fabric the embedded warp-threads ab and thethreads .9 and c are practically invisible. The warp-threads a areagitated sidewise from one side to the other to give them a zigzag formin the fabric and place them alternately to the right and left of thewarp O, as shown in Fig. 1, producing therebya higher tension and asecurerlock, the needle-heddle that carries the warp a entering, forexample, on op- 6 5 posite sides of the thread 0, as in Fig. 1. Thewarp-threads b may be agitated in like manner.

One mechanism by which I construct this fabric is shown and described inthe application bearing SerialNo. 393,383, filed by me on the 20th dayof May, 1891. Fig. 5 gives one view of said mechanism, showing atA thebatten, at B the shuttle, at O the heddle for the warp a, at D theheddle for the warp b, at E the guide for the warp-thread c, at F and Gthe carriers forthe cordsjj respectively, and at H a beam around whichthe finished fabric passes.

Having thus described my invention, what I claim is A fabric consistingof two main warpthreads 0, b, an intermediate warp-thread c, face-cordsjj and the weft-thread s, the warp abeing placed under theweft-threadson op- 8 5 posite sides of the warp c alternately and beinglaid over the cords j and under the weft s, the warp b passing over theweft s and under the cords j all substantially as and for the purposespecified.
